[MPlayer-users] SIGSEGV initializing m3jpeg32.dll, goes away with --enable-debug

Hi,

Both 0.90pre5 and CVS-020803 mplayers crash initializing m3jpeg32.dll
when playing MJPEG files made with a Matrox G400-TV (using either PC-VCR
[MS-Windows] or lavrec [Linux]).  But the problem goes away when MPlayer
is configured --enable-debug! I am using GCC-3.1 and v0.6 win32 codecs.


Output & Trace for non-debug compile:
